Chp 15 Nervous System and Behavioral Health - Organs

Question 1

Brain

Answer 1

Contained within the cranium, the center for coordinating body activities, and comprises the cerebrum, cerebellum, and brainstem.

Question 2

Cerebrum

Answer 2

Largest portion of the brain, is divided into left and right hemispheres.

Question 3

Grey Matter

Answer 3

Outer portion of the cerebrum contains neuron cell bodies that collect the process information.

Question 4

White Matter

Answer 4

Inner portion of the cerebrum, contains axons, and long cords that extend from neurons; convey information to different parts of the brain.

Question 5

Ventricles

Answer 5

Cavities (spaces) within the brain that contain cerebrospinal fluid (CSF).

Question 6

Cerebellum

Answer 6

Located under the posterior portion of the cerebrum; assists in the coordination of skeletal muscles to maintain balance (also called hindbrain)

Question 7

Brainstem

Answer 7

Stemlike portion of the brain that connects with the spinal cord; contains centers that control preparation and heart rate

Question 8

Pons

Answer 8

Means bridge. It connects the cerebrum with the cerebellum and brainstem

Question 9

Medulla oblongata

Answer 9

Located between the pons and spinal cord

Question 10

Midbrain

Answer 10

Most superior portion of the brainstem

Question 11

Cerebrospinal fluid (CSF)

Answer 11

Clear, colorless fluid is contained in the ventricles flows through the subarachnoid space around the brain and spinal cord.

Question 12

Spinal cord

Answer 12

Passes through the vertebral canal extending from the medulla oblongata to the level of the second lumbar vertebra.

Question 13

Meninges

Answer 13

Three layers of membrane that cover the brain and spinal cord

Question 14

Dura Mater

Answer 14

Tough outer layer of the meninges

Question 15

Arachnoid

Answer 15

Delicate middle layer of meninges

Question 16

Pia Mater

Answer 16

Thin inner layer of the meninges

Question 17

Nerve

Answer 17

Cordlike structure made up of fibers that carry impulses from one part of the body to another.

Question 18

Ganglion

Answer 18

Group of nerve cell bodies located outside the central nervous system

Question 19

Gila

Answer 19

Specialized cells located throughout the nervous system support and nourish nervous tissue.

Question 20

Neuron

Answer 20

Nerve cell conducts impulses to carry out the function of the nervous system.
